First report of Peanut stunt virus on beans in Bulgaria.
In 2013, leaf samples with virus-like symptoms were collected from beans (Phaseolus vulgaris) in fields around the Maritsa Vegetable Crops Research Institute and in private gardens in regions near Plovdiv, Bulgaria. Disease incidence varied from 10-50%. Symptoms consisted of green or yellow mosaic, blisters, and leaf distortion. In some locations the prevalent disease was associated with severe stunting. Based on molecular data (nucleotide sequences and phylogenetic analysis), the causal pathogen was identified as Peanut stunt virus. This is thought to be the first report of Peanut stunt virus on P. vulgaris in Bulgaria.
